SPECIFICATION forming part of Letters Patent No. 762,157, dated June 7, Application filed July 25,1903. $erial No. 167,037. (No model.)

To all whom it may concern.-

Be it known that I, GLEN M. DYE, a citizen of the United States, residing at Poynette, in the county of Columbia and State of Wisconsin, have invented new and useful Improvements in Bean-Picking Tables, of which the following is a specification.

My invention relates to new and useful improvements in bean-picking tables; and its object is to provide a machine of simple and inexpensive construction which is adapted to be operated by a foot of the person engaged in picking the beans upon the machine.

A further object is to provide means for operating a conveyer-apron whereby beans are brought into position adjacent-the operator.

A further object is to employ an arrangement of troughs for carrying away beans of different grades after they have been assorted manually.

WVith the above and other objects in view the invention consists in the novel construction and combination of parts hereinafter Figure 1 is a side elevation of my improved machine. Fig. 2 is a plan view thereof. Fig. 3 is a section on line 3 8, Fig. 2. 4 is a section on linea Fig. 3. Fig. 5 is a section on line 5 5, Fig. 3; and Fig. 6 is a section on line 6 6, Fig. 2.

Referring to the figures by numerals of reference, 1 1 are standards connected by means of suitable cross-braces, so as to form a frame, upon which is located a bed 3, having rollers 1 and 5 journaled therein adjacent opposite ends. with a ratchet-wheel 6, and the opposite sides of this ratchet-wheel are normally engaged by oppositely-arranged pawls 7 which are pivoted to lovers 8 and are held normally in engagement with the ratchet-wheel by means of springs 9. The strips 8 are pivoted to the rear end of a treadle 10, mounted within the frame and adapted to be operated by the person engaged in picking beans. An endless apron ll-is arranged on the rollers 4L and 5,

The roller 5 is secured to and rotates and a strip 12 extends under the upper por- 5 tion of the apron between the rollers 41: and 5 and serves to support it normally in a horizontal position. v

A chute 13 extends downward from the forward portion of the bed 3, and its inlet is of sufficient width to receive articles which may be in any position upon the apron 11. This chute extends to the rear end of the machine and is preferably covered, so as to prevent articles from jumping therefrom after being once deposited therein. Asuitable receptacle may be provided at the discharge end of this chute for the reception of the material conducted thereby. Inclined troughs 1a are arranged at the sides of the bed 3 and are adapted 5 to conduct any material deposited therein rearward to a chute 15, which extends transversely of the machine under the apron 11 and has a discharge-spout 16. A hopper 17 is located above the roller 5 and is provided 7 with an inclined bottom 18, the forward end of which, as well as the front face of the hopper, is cut away to form an outlet 19. In front of this hopper is pivoted a lever 20, having downwardly-extending prongs 21 thereon, which extend across the outlet and are for the purpose hereinafter more fully described.

In operating the machine herein described the beans to be separated or picked are placed within the hopper l7 and are guided down- 30 ward by the inclined bottom 18 through outlet 19, from which they drop upon the apron 11. The operator places one or both feet upon the treadle and swings the same upon its pivot. Upon the downward stroke of the 3 5 rear end of the treadle the forward pawl 7 will slip over the teeth of the ratchet-wheel 6, while the rear pawl 7 will engage said teeth and cause the wheel to partly rotate. When the motion of the treadle is rev-ersed,the other 9 pawl will engage the teeth, and, as is obvious, in this manner the ratchet-wheel is caused to rotate in one direction ata desired speed. As will be readily understood, the apron 11 will be carried outward from under the outlet of the hopper by the rotation of the roller 5, to which the ratchet-wheel is connected, and the beams discharged from the outlet will therefore be brought into position between the troughs 1 1 and to a point where they can be readily reached by the operator. The prongs 21 serve to spread the beans upon the apron, and the bad ones can thus be readily detected and removed from the apron by the operator and placed in one of the troughs 14. These troughs, as hereinbeforc stated, guide the beans to the chute 15, from which they are discharged through spout 16. The beans which are left upon the apron are carried forward thereby and finally deposited in the inlet of the chute 13 and conveyed by this chute to the rear of the machine.

It will be seen that this machine is very simple and inexpensive in construction, and one person can drive the apron and pick the beans conveyed thereby. The beans may be carried from the hopper in desired quantities, according to the speed of the apron. It will be understood that any desired form of mechanism may be substituted in lieu of the pawls and ratchet above described.

In the foregoing description I have shown the preferred form of my invention; butl do not limit myself thereto, as 1 am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus described the invention, what is claimed as new is 1. In a machine of the character described, the combination with ahopper having an outlet; of a lever pivoted to the hopper adjacent the outlet, oppositely arranged prongs depending from the lever and arranged in alinement with the outlet, an endless apron extending from the outlet, and means for operating the apron.

2. In a device of the character described, the combination with a hopper having an outlet; of a lever pivoted to the hopper adjacent the outlet, oppositely-arranged curved prongs depending from the lever and in alinement with the outlet, said prongs forming spreading devices, an endless apron extending from the outlet, means for operating the apron, inclined troughs at the sides of the apron, an outlet-chute communicating therewith, and a chute extending from the front of the apron to the rear of the machine.

3. In a machine of the character described, the combination with a hopper having an outlet, a lever pivoted to the hopper adjacent the outlet, and oppositely-arranged prongs depending from the lever and in alinement with the outlet; of rollers, an endless apron mounted upon the rollers and extending from the outlet, a ratchet-Wheel connected to one of the rollers, oppositely-arranged pawls at the sides of and normally engaging the ratchetwheel, a treadle, and rods connecting the treadle and pawls, whereby a continuous rotation of the ratchet-wheel in one direction may be produced.

4. In a device of the character described, the combination with a hopper havingan outlet, a lever pivoted to the hopper adjacent the outlet, and oppositely-arranged prongs depending from the lever and in alinement with the outlet; of rollers, an endless apron mounted upon the rollers and extending from the outlet, a ratchet-wheel connected to one of the rollers, pawls at opposite sides of and normally engaging the ratchet-wheel, a foottreadle, rods connecting the treadle and pawls,

inclined troughs at the sides of the apron, an

outlet and chuteeommunicating therewith,

and a chute extending from the front of the apron to the rear of the machine.

In testimony whereof I affix my signature in presence of two witnesses.

GLEN M. DYE.
